Beinn Trilleachan
Beinn Trilleachan rises above the head of Loch Etive, its 840m summit overshadowed in mountaineering folklore by what's underneath: the Etive Slabs, the longest sustained granite slab in Scotland and a Mecca for rock climbers since the 1950s. The walking ascent from the loch-side road gives a fine short day, climbing onto a broad ridge with views back across Loch Etive to Buachaille Etive Mòr and the Glen Coe peaks. The hill's name means 'mountain of the oystercatchers' — the sandy shore of the loch below was once a sea-bird haunt.

Standard route
loch-side path 15% · steep grass 40% · heather hillside 30% · summit area 15%
From the small parking area at the head of Loch Etive (the road end past Coileitir), follow the lochside track south-west for around 1km. Leave the track and climb steeply north-west up grass and rock onto the south-east ridge of Beinn Trilleachan. The route gains height quickly and reaches the broad summit ridge, with a short walk west to the cairn. Allow 5–6 hours. The climber's start for the Slabs is from the same parking area but heads directly up the loch shore.
Terrain
Lochside track for the first kilometre. Above that, the ascent is steep grass with rock outcrops and a few short scrambly steps. The slabs themselves are clearly visible to the south but are climber's terrain — walkers should stay north of them. The summit ridge is broad and grassy with a clear cairn.
In winter
In winter the south-east ridge gives a steep snow ascent in good conditions. The Etive Slabs become unclimbable until well into spring; for walkers this is not relevant but the iced slabs are an impressive sight from the ridge above. The Glen Etive road can be slow and is sometimes closed by snowfall.
This hill is in the Glen Coe SAIS forecast area. Check SAIS forecasts in winter (December–April).
